ADJUSTING DEVICE FOR OIL-WELL PUIVIPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. I763,621, dated June 28, 1904. Application filed January 3, 1903. Renewed April 13, 1904. Serial No. 203,039. (IIo model.)

T0 a/ZZ whom, tn/Lay oon/00771,.'

Be it known that I, FRANKLIN PIERCE MYERS, a citizen of' the United States, residing at Trailrun, in the county of Monroe and State of' Ohio, have invented a new and useful Improvement in Adjusting Devices for Oil- Well Pumping Apparatus, of which improvement the following is arspecification.

This invention relates to an improved device used in connection with oil-well pumping apparatus; and it consists in a means whereby the valve in the working barrel below may be adjusted at the top of' the well without disconnecting any of the parts, together with the certain details of' construction and combination of parts, as will be fully described hereinaftcr.

In the accompanying drawings, Figure 1 is a sectional side elevation of my improved device, partly in elevation, the'said view being constructed and arranged in accordance with my invention. Fig. 2 is an enlarged side sectional elevation of' the ball connection, together with its connected parts. Fig. 3 is a sectional plan view of' the same, the said section taken on the line ofl Fig. 2.

In the drawings the numeral 1 indicates the tubing of an oil-well, which extends downward to the bottom of the well and is yfitted with a working barrel, a standing valve, and sucker-valve, all in a manner Well known in the art. Connected to the top of the tubing 1 isa fitting 2, having a branch pipe 3 leading to the tank in which the oil from the well is pumped and the said fitting provided at the top with a stuffing-box 4, through which` the polish-rod 5 operates, the said rod being connected to the sucker-rods in the usual manner. Attached to this polish-rod 5 is a clamp 6, held rigid with the said rod by a set-screw'?, and the said clamp formed with a threaded portion in which a short section of tubing 8 is secured. This tubing is connected to a sleeve V9, threaded at both ends, the upper end of which is fitted with a gland 12 and jam-nut 11. Loosely arranged within this gland 12 is a tube 10, provided with a screw-thread at its lower end and also with an enlargement 13, the said screw-thread serving the double purpose of attaching the enlargement 13 and to operate the jam-nut 11. This tub'e 10 is fitted with a handle 14 or other suitable lever and is formed with a screwthread extending its entire length above the said handle-bar or lever 14. Operating upon this last-described threaded portion of the tube 10 is a fitting 12', which may be locked at any position by a jam-nut 13' and the said fitting formed with a threaded socket in which a section of tubing 15 is attached, the said tubing having attached to its upper end a means 15 of connection with the walkingbeam of the well. The said beam when in motion will give the device, together with the sucker-rods and their connected parts, a vertical or up-and-down movement.

In operation if' it is desired to adjust the valve operating within the working barrel the jam-nuts 11 and 13 are loosened, and by revolving the handle-bar 14 in the desired direction the said valve may be raised or lowered to the proper position. The connection at the base of the tube 10 will permit a free movement of the same. After the said valves are in position the jam-nuts 11 and 13 are tightened to lock the parts in position.

Various slight modifications and changes may be made in the details of construction without departing from the spirit of the invention. lfherefore I do not confine myself to the exact construction shown and described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is*

The herein-described device for oil-well, consisting of the combination of the polishrod 5, the grip 6 and means for attaching the same to the polish-rod, a threaded socket formed in the said grip, a short section of tubing 8 engaging with the said socket, a sleeve 9 attached to the said tube, a threaded gland 12 placed in the top of the sleeve, said gland adapted to coniinea section of tubing 10 therein, the said tube being provided with an enlargement 'end 13 and loosely connected, a jam-nut 11 to prevent the tube from turning, a handle-bar 14 attached to the tube10, a threaded socket 12 and jam-nut 13 operatmy name in the presence of two subscribing Witnesees.
